Since the middle height of the outer paddle 2 connecting plate is higher than the height of its two ends, the bottom materials are drained upward and tend to flow, so as to improve the uniformity of material mixing;
[0028] The inner paddle 3 is located inside the outer paddle 2 and includes an inner paddle 3 mounting column. Two inner paddles 3 are symmetrically arranged on the inner paddle 3 mounting column. Both inner paddles 3 are fixedly connected to the inner paddle 3 mounting column. The inner paddle 3 is located inside the outer paddle 2 and remains relatively still with the outer paddle 2. It is fixedly connected to the stirring shaft 1 through the inner paddle 3 mounting column, so that the rotation of the motor drives the outer paddle 2 and the inner paddle 3 to rotate synchronously. Since the inner paddle 3 is located inside the outer paddle 2, when stirring in the tank body, stirring of materials at different positions in the tank body is achieved, stirring of the materials in the tank body is achieved, and the uniformity of material stirring is further improved.
[0029] Please refer to Figure 2 As shown, an outer paddle 2 mounting hole is formed inside the outer paddle 2 mounting column, and the outer paddle 2 mounting column is fixedly connected to the stirring shaft 1 through the outer paddle 2 mounting hole. The outer paddle 2 mounting column is cylindrical, and the outer paddle 2 mounting hole is formed inside it for connecting the outer paddle 20 and the stirring shaft 1, so that the stirring shaft 1 drives the outer paddle 20 to rotate in the tank body, thereby achieving stirring and mixing of the materials.

On the one hand, the material at the bottom of the tank body can be stirred to avoid uneven stirring of the bottom material. On the other hand, the guide plate 24 can push the material under the guide plate 24 upward to a certain extent, and can stir the upper and lower layers of materials, thereby improving the stirring effect on the material.
[0032] Please refer to Figure 1-2 As shown, there are two guide vanes 24, which are continuously distributed along the length direction of the outer paddle 2 connecting plate and are symmetrical along the center point of the bottom surface of the outer paddle 2 connecting plate. The two guide vanes 24 are located on both sides of the outer paddle 2 connecting plate, and can achieve uniform stirring of the material at the bottom of the tank body when the stirring shaft 1 rotates in different directions.
[0033] Please refer to Figure 3 As shown, an inner paddle mounting hole 33 is formed inside the inner paddle 3 mounting column, and the inner paddle 3 mounting column is fixedly connected to the stirring shaft 1 through the inner paddle mounting hole 33. The outer paddle 2 mounting column is located at the end of the stirring shaft 1 away from the planetary gear 11. The inner paddle 3 mounting column is fixedly connected to the stirring shaft 1 through the inner paddle mounting hole 33, so that the motor drives the inner paddle 3 mounting column to rotate. Since the two inner paddles 3 are fixedly connected to the inner paddle 3 mounting column, the motor drives the inner paddle 3 to rotate. A distance is formed between the outer paddle 2 mounting hole and the inner paddle 3 mounting column to avoid interference between the outer paddle 2 and the inner paddle 3 during rotation.
[0034] Please refer to Figure 1-3 As shown, the shape of the inner paddle 3 is the same as that of the outer paddle 20, and the size of the inner paddle 3 is smaller than that of the outer paddle 20.

[0035] Please refer to Figure 4As shown, the axis of the inner paddle 3 connecting plate in the length direction forms an angle A with the axis of the outer paddle 2 connecting plate in the length direction, and the angle A satisfies: 110°<A<130°, so that a certain alternation is formed between the outer paddle 2 and the inner paddle 3 to increase the contact area between the four rows of stirring paddles and the material, thereby improving the stirring effect on the material.
[0036] Working principle of this utility model:
[0037] The bottom of the bearing 12 is fixedly connected to the top of the tube body, and the planetary gear 11 is meshed with the gear at the output end of the motor, so that the rotation of the motor drives the rotation of the stirring shaft 1 through the planetary gear 11. Since the outer paddle 2 and the inner paddle 3 are fixedly connected to the circumference of the stirring shaft 1, the rotation of the motor drives the outer paddle 2 and the inner paddle 3 to rotate synchronously in the tank body, so as to stir the material;
[0038] Among them, one end of the outer paddle blade 20 is fixedly connected to the outer paddle 2 mounting column, and the other end is fixedly connected to one end of the outer paddle 2 connecting plate. Two outer paddle blades 20 are symmetrically arranged on the circumferential surface of the outer paddle 2 mounting column. The two outer paddle blades 20 and the outer paddle 2 connecting plate are connected end to end to form a closed loop. The outer paddle blade 20 is in a curved spiral shape. The spiral shape can enable the outer paddle blade 20 to push the material upward under rotation, and at the same time, perform a circular motion along the tank body, thereby realizing the flow of the material up and down and left and right, thereby realizing the stirring of the material. Among them, the outer paddle 2 connecting plate is an upwardly protruding triangular prism, and is connected to a guide plate 24 of a triangular prism structure at the bottom. The guide plate 24 and the outer paddle 2 connecting plate can perform a circular circulation of the material at the bottom of the tank body. Due to the formation of an inclined surface, the material can be pushed and drained upward, thereby realizing uniform stirring of the material at different positions of the tank body, thereby improving the uniformity of material stirring;
[0039] Three inner paddles of the same shape and smaller than the outer paddle blades 20 are formed inside the outer paddle 2, and form a certain alternating angle with the outer paddle 2. The outer paddle 2 and the inner paddle 3 rotate synchronously, and the materials of different diameters in the tank are mixed and stirred respectively through the outer paddle blades 20 and the inner paddles 3, so as to achieve mixing of the materials, further change the contact and mixing of the materials between the inner and outer layers of the materials, and improve the stirring effect of the materials.
